Health warning:

This nematode has been found inside the stomach of humans!
See Chandler (1938). Presumably, these were cases
of worms surviving accidental ingestion after stomach inactivation through
some other cause, but nevertheless: handle with due care - avoid all risks
of inadvertently swallowing worms!

Long-term storage:

Can be frozen in glycerin (very low efficiency).

Availability:

Freely available on agar.
